Changes since version 1.5.1
 General:

Check for the existence of the database at simulation start and give appropriate error
message.
 Remove check of ATM and PSC schema version.
 Compare the used OpenTrack version with the OpenPowerNet compatible OpenTrack
version. If the versions are different a warning is displayed in APserver.
 As the use of moving block is not recommended when running OpenTrack with
OpenPowerNet. A course following a slow course requests alternating maximum brake
effort and maximum tractive effort over time and this spoil the load flow simulation. If
courses do not hinder each other the use of moving block is possible but the user
needs to carefully analyse the effort requests for each course! Therefore a warning
message (APS-W-005) is generated for each time alternating effort requests are
detected. This may give the user a hint to look for the course following a slower course.
 The debug message logging is now possible to disable (default) in GUI preferences.
The disabled debug message logging speeds up the simulation significant.
 Power supply system AC 25 kV 60 Hz and none standard power supply systems
added, see User Manual chapter 6.5 on how to use.
 Bugfix: License was still occupied after module shut down for 3min and therefore
single license was blocked to be used within this 3min.
 Bugfix: A modified databaseSchema value in the Project-File did not have effect for a
2nd simulation in still running modules. The workaround was to stop and restart the
modules for each simulation.
 Database:
 none
 ATM:
 Remove info message of reduced auxiliary power for constant current and constant
voltage engines.
 Remove info message from ATM of new and died course because the same message
is displayed at APserver.
 Bugfix: In some cases the storage was not charged in recovery mode when pantograph
current was small positive due to iteration inaccuracy.
 PSC:
 Rename Network options attribute from discreteTrains to discreteEngine with slightly
changed behaviour. The default value of discreteEngine is true and allows not discrete
(false) engines now only for DC networks as originally intended. For AC networks it's
not possible to split the current between two neighbouring slices due to the unknown
and different voltage/current angle at the slices.
 Restrict usage of transformer models to AC networks only.
 Bugfix: Station energy storage was sometimes not charged in case of multiple storages
in one network.

Release Notes Version 1.5.2
Issue 2014-05-08
 Bugfix: Very seldom error message during PSC start up because of not initialised
pointer.
 Bugfix: The dump file recording was corrupt in 1.5.1 as the time was always 0.
 GUI:
 Remove dump file upload command from menu and toolbar as dump files do not have
advantage since 1.5.1 over directly recording data into the database. Upload is still
available from context menu when selecting a project file.
 Selection Editor:
 File is saved when clicking "Start Analysis".
 Substation: Split Aggregation selection in Chart and Overview(Tables).
 The minimum selectable time interval should be one time step. If less the wrong
configuration is highlighted in red. This applies to the times on the General page as
well as for Magnetic Field.
 Bugfix: MagneticField: min and max of times have not been set to correct values.
 Excel Analysis:
 Add P=f(s) to Engine.xlsx, Engine2.xlsx and EngineAll.xlsx.
 Analysis Tool:
 Output for substations
 Complete makeover. Also removed unnecessary data columns like phase in degree
to speed up output creation and columns for S and Q in overview for DC networks.
Separate charts for power output and input are only created if device can recover
energy to the national power grid.
 Chart output for power of threewinding and autotransformer (2AC system) now
contains separate series for both subdevices (OCS-Rails and Rails-NF). The
previously known output for power of autotransformer is now shown as "Loss". This
also applies to values for autotransformer in overview table.
 Subdevice and busbar names in legend for threewinding and autotransformer (e.g.
OCS-Rails and Rails-NF) are now created using busbar types instead of names.
These can be modified in preset under strings (e.g. OCSBB, RailsBB). The item title
may be modified using new placeholder %_subDeviceID% and %_busbarType%.
The old placeholders are deprecated.
 For the booster transformer chart U,I = f(t) and TRLPC the items I_BusbarPrimary2
and I_BusbarSecondary2 were previously disabled in source code as they are
usually identical to corresponding 1. Now the optional attribute "use" can be set to
true if needed. The placeholders in item titles have been updated to match other
output, old ones are deprecated.
 Using "file production mode" also for overview and aggregation now.
 Overview tables
 Title and subtitle are now created inside top left cells with left alignment. This is
necessary to support more character sets. To enable the previous behaviour, set
optional preset attribute "titleInHeader" under Settings/Excel to true!
 Wide tables, which would not fit on single page width, are now automatically scaled
down. To enable previous behaviour, set optional preset attribute "fitToPagesWide"
under Settings/Excel to 0.
 Added optional attribute "createDescriptionPage" to preset element "TableType" to
disable creation of description page when not needed.

Release Notes Version 1.5.2
Issue 2014-05-08
 Added optional attributes "emptyValueString" and "emptyValueDescription" to preset
element "TableType" which are used if a value could not be added to an overview
tables due to missing data, e.g. simulation time was too short for “rms15” values.
 Added possibility to select the time base of the former "rms15" values. These items
are now renamed to "rmsSel" (I_rmsSel and P_rmsSel). The customised time base
may be set through new optional attribute "selectionValue" (in s), "title" and
"description" may be adopted accordingly.
 Display thousands separator. For losses display only one decimal.
 Added horizontal and vertical border lines to visually separate the different sections.
This may be disabled by setting optional attribute "borders" under element
"TableType" in preset to false.
Output for vehicles:
 Shortened item names to better fit the page. Energy ratio items are now called ξ (xi)
instead of η (eta) to separate them from efficiency.
 Added travelling time to overview.
 Calculate U_mean_useful for course according to DIN EN 50388:2012-12.
 Particular columns may be disabled in preset using attribute "use".
Output for lines
 Items like substation feeders, isolators and stations are not only shown for the
selected tracks but for the whole selected line now.
 Leakage current: Now using default unit A/km, may be changed back to A/m in
preset if necessary.
Output for magnetic field
 Added grid lines to the image for better readability. These may be defined in preset
under xAxis and yAxis elements using the attributes "gridMajor" and "gridMinor". In
the default preset major grid is enabled and minor grid is disabled.
General Excel output
 The sheet name is not printed to the centre footer anymore. To enable the previous
behaviour, set optional preset attribute "sheetnameInFooter" under Settings/Excel to
true!
 Draw a marker for chart series if selected time scope contains only a single timestep
and no line can be drawn.
 Handle long sheet names (31 characters is maximum). Data sheet prefix is now D|
instead of DATA_, text label prefix is now T| instead of TEXT_ to preserve some
characters.
 Using english sheet names now because unicode is not supported by Excel.
Added support for system "AC 25kV 60Hz". Additionally a system "other" may be
defined in preset for any custom system.
Added check for database tables with disabled keys, e.g. from an aborted simulation,
they are re-enabled if necessary to speed up reading from disk.
Degraded warning about increasing or reducing axis scale to info.
Bugfixes
 Output for f(t): Axis setting could be wrong if attribute "use" of particular items was
set to false in preset.

Known restrictions
OpenPowerNet is tested with OpenTrack version 1.7.4 (2014-02-05) and should only be
used with this version.
OpenPowerNet is a single user application. It is not tested to use the same database for
multiple users at the same time.
The Engine-File uses the RailML rollingstock schema version 1.03 with OpenPowerNet
specific extensions and is therefore not 100% compatible with the mentioned version 1.03.

Known issues
The following table contains all known but unsolved issues.
ID
Summary
When using larger time steps other than 1s, OpenTrack sends the
requests not for all courses in the same time raster but
OpenPowerNet is designed to calculate always in the same time
raster.
Workaround 1: Use always 1s simulation time steps.
371
Workaround 2: Set all times within OpenTrack in the raster
according to the selected simulation time step, e.g. for 3s time step
only time hh:mm:00, hh:mm:03, hh:mm:06 …..
The simulation will be terminated by OpenPowerNet in case of
OpenTrack requests outside of the time raster.
The information of split, merged and connected courses is not
available in OpenPowerNet. Therefore the engine energy storage of
458 an engine will be reset to the initial values even if the new course is
connected with the previous course and the two courses represent
the same physical train.
Creation of magnetic field image needs the desired character set to
582 be used for output set as system locale as Matlab plot functions do
not handle unicode characters.
